The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity. The longer wavelengths enable Webb to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies, as well as to look inside dust clouds where stars and planetary systems are forming today.
With the conclusion of the year just days away, we are excited to announce #NASAWebb has cleared one of its most important testing milestones to date. Webb’s 5-layer sunshield has been successfully deployed and tensioned into the same configuration it will have once in space! Image Credit: NASA/Chris Gunn
Another shot of the successful recent sunshield test. Webb is now in its final series of deployment and checkout tests before the observatory is packed for shipment to French Guiana for launch aboard an @ArianeGroup Ariane V rocket. These tests will verify that Webb will deploy perfectly in space after its launch. Image credit: NASA/Chris Gunn.
The James Webb Space Telescope has completed two of its last deployment tests at Northrop Grumman in Redondo Beach, CA. Engineers deployed the forward and AFT pallets that hold Webb's sunshield during launch. Engineers then deployed the Webb's central tower, lifting Webb's mirrors and instruments. Webb is now ready for the next phase of tests, deploying the most delicate part of the spacecraft, the sunshield. Video Credit: NASA's Goddard Space Flight Center.
